From the specification, a coupling fitting of the first type mentioned is known, in which the drive for the wedge-shaped arcuate piece is constructed in the form of a disc, so that it does not rotate relative to the pivot axis area, for example by means of a press fit or a shrink fit. Is bound to. The disk-shaped driving body is integrally formed and has a driving projection that acts on the narrow circumferential end surface of the wedge-shaped arc-shaped piece. The disk-shaped carrying member having such a configuration cannot be easily manufactured because of a sudden change in radius in the range of the carrying protrusion. A transmission rod is provided to transmit torque from a joint metal fitting provided on one vertical side of the seat to a joint metal fitting provided on the opposite vertical side of the seat, and a non-rotating shaft on each vertical side of the seat is provided. It fits in a circular recess, thereby connecting both fittings to each other. It has oscillating shaft pins, with one joint part being supported directly on the pin area of each oscillating shaft in the form of a rotary joint and the other joint part being directly supported on the wedge-shaped arc. In the case of collision, these joint portions have a thickness that slightly exceeds the necessary tooth thickness for reasons of strength, so that a relatively large surface pressure is generated at the supporting portion of the joint fitting.

から突出する連行腕２２に続いている。The entrainment body 20, which is preferably integrally formed from plastics, includes a boss 21 rotatably supported on the outer periphery in the collar 19 of the joint portion 12, and partially encloses the collar 19 and radiates from the boss 21. The pulling arm 22 provided separately in the direction is connected to the boss 21.
Similar to the boss 21, 2 is connected to a cover plate 23 that covers the joint range on the axially outer side of the joint fitting 10. Two wedge-shaped arc-shaped pieces 24 are supported on the inner peripheral surface of the collar 19 in the plane of the driving arm 22, and the outer peripheral surface of the spur gear 15 of the joint portion 11 is the inner peripheral surface of the support collar 25. Is in contact with. The narrow circumferential end face of the wedge-shaped arc-shaped piece 24 is slightly apart from the driving arm 22 in a fixed state of the joint fitting, and the wide circumferential end-faces of the wedge-shaped arc-shaped piece 24 are pushed apart from each other by an annular spring. It is subjected to the action of the spring leg side 27 of 26. These wedge-shaped arcuate pieces 24, together with the collar 19 of the coupling part 12, form an eccentric ring region 14, by means of which the internal teeth 18 of the coupling part 12 extend outside the ring gear 17 at the extension of the eccentric ring maximum. It is pushed into the tooth 16. In the region of the wedge-shaped arc-shaped piece 24, one contact surface 28 having a wedge-shaped arc-shaped profile is integrally formed on both sides of the boss 21 adjacent to the cover plate 23.
It continues to the take-up arm 22 protruding from.

受けないからである。The boss 21 of the carrying body 20 has a receiving portion formed in the center thereof as a conical hole 29, and has a conical peripheral surface that slightly expands toward the inside of the seat, and the conical peripheral surface has the smallest diameter. , On the side adjacent to the cover plate 23. In this embodiment, the conical hole 29 has a modified spline cross section for transmitting torque, and a transmission rod 30 having a modified spline cross section is fitted into the conical hole 29. The conical hole 29, which serves to receive the transmission rod 30, has a conical peripheral surface which can be inclined up to about 3 ° with respect to the central axis of the conical hole 29. As a result, centering errors of the centers of both joint fittings facing each other are canceled out. This is because during the adjustment movement of both joint fittings, a cardan function is generated within a small but sufficient range, so that the coupling between the driving body 20 and the transmission rod 30 is not significantly subjected to the force. is there.
